At Environmental Defense Fund (EDF), we understand that market forces can drive either a healthy environment – or harmful pollution. I recently wrote about how generating electricity often creates pollution, which comes with environmental and health costs that are usually not paid for by the polluters. That’s why EDF works to identify and correct market failures, like the failure to understand – as well as account for – all of the costs pollution imposes on society.

The Energy Institute at the University of Texas at Austin (UT) just released a useful tool in that pursuit: a study that aims to capture the full cost of new electric power generation – including environmental and public health costs – on a county-by-county basis in the United States. The study evolves traditional ways of estimating new generation costs by 1) incorporating pollution costs, and 2) breaking data down to the county level.

The results show economics are leading the U.S. to a cleaner energy economy, in which there is no role for new coal plants. Let’s break it down. Read More »

The city of El Paso has many nicknames, but “The Sun City” is probably the most well-known. After two important energy updates this summer, West Texas’ largest city has even more reason to call itself that.

First, El Paso Electric, the public utility that serves nearly half a million customers, reached a major milestone: It is now officially 100 percent coal-free and has pledged to increase its solar investment. Second, the utility agreed to eliminate its proposal that would have resulted in different electricity prices for customers with solar panels at their homes. Such a pricing structure would have placed an unnecessary burden on El Pasoans with solar.

Sunny El Paso has incredible potential for solar power, and both of these developments are positive signs for the city’s clean energy future. Let’s take a closer look at each.

Austin, my home for the past 35 years, is typically a pretty sunny place year-round. But summer is when I am reminded of the sun’s unwavering presence and strength.

Fortunately, Texas is beginning to put those rays to work, as evidenced by GTM Research and the Solar Energy Industries Association’s (SEIA) newest U.S. Solar Market Insight. Along with projected scenarios from the state’s main grid operator and a recent poll of Texas voters, the report confirms the Lone Star State’s solar power is on an unstoppable course. And the more we can take advantage of the sun’s energy, the less we have to rely on outdated, polluting coal plants – a good thing for our health and water.

Here are three reasons Texas solar is on the rise:

Texas solar is growing very quickly: The new Solar Market Insight report declares Texas to be the fastest growing utility-scale solar market in the country. In fact, by the end of 2016, SEIA predicts the state’s total installed solar capacity will more than double. And within the next five years, Texas’ solar market will be second only to California’s (although, considering California has one-fourth of the solar power potential of Texas, we could eclipse the Golden State in coming years).

Last year solar power saw unprecedented growth and it doesn’t seem to be slowing down. So where is much of this growth happening? In one word: cities.

In a new report from Environment America Research & Policy Center and Frontier Group, Shining Cities 2016 identifies the urban centers fostering growth in solar energy, and the policies and programs that can maximize solar potential. The cities that topped the list were, not surprisingly, primarily from the sunshine-abundant Pacific region, followed by an equal amount of cities from the Mountain, South Central and South Atlantic regions. These centers of connectivity and growth are major electricity consumers, and therefore important movers in the transition to a clean energy economy.

But there are still vast amounts of untapped solar potential in the U.S. – specifically 1,118 GW, which equates to 39 percent of total national electricity sales (enough to power over 782 million homes a year) – according to a study on “rooftop solar power generating capacity potential” by National Renewable Energy Laboratory (NREL). The same study stated that Los Angeles, the city currently with the most solar capacity, could host up to 42 times its current solar capacity, providing up to 60 percent of the city’s electricity. This staggering amount of renewable energy is possible in other cities across the U.S. as well – even in unlikely states, such as Texas. Read More »

In terms of clean energy, Texas is incredibly resource-rich. And as our wind progress shows, we have begun to maximize that potential: A new report from the American Wind Energy Associations shows the Lone Star State leads the nation with over 24,000 wind energy employees.

How did Texas arrive at the forefront of the wind energy economy? One factor that undoubtedly played a vital role: the creation of an ahead-of-its-time policy tool that required the identification of Competitive Renewable Energy Zones (CREZ), as well as the construction of transmission lines to move energy from the CREZ to electric customers.

Since West Texas has plentiful wind but not as many people, this initiative aimed to transport that wind energy to populous cities throughout the state. The rules allow the Public Utility Commission of Texas (PUCT) to designate an area with abundant renewable energy as a CREZ, and then approve new transmission lines or improvements to existing ones. In 2008, the PUCT exercised this authority and the resulting power lines – completed in 2014 – stretch nearly 3,600 miles, moving clean, renewable energy across the state while improving the overall reliability of the electric grid.

However, despite these successes, the PUCT recently proposed to dismantle the rules related to CREZ and the approval of new transmission lines, which would be a significant affront to the state’s thriving wind industry – including the revenue and jobs that come with it. Right now, there are no proposals to expand the designation of CREZ and develop additional power lines to those zones. But with the rapidly changing energy landscape, it makes more sense for state leaders to maintain CREZ capabilities in their toolkit, rather than undoing a successful energy development policy.

Symbiosis – in which different species have a cooperative or mutually beneficial relationship – is everywhere in nature: honeybees receive vital nutrients from flowers while delivering pollen (male) directly to the female parts of the flower; pilot fish gain protection from predators, while sharks gain freedom from parasites; and dogs protect their owners, while receiving food and shelter. Cited by some scientists as a major driver of evolution, symbiosis has played an important role in the mutual survival of certain species.

Two elements in nature that are also very symbiotic are energy and water: It takes water to produce and distribute energy, while energy is used to treat, pump, and distribute water. This inextricable link is known as the energy-water nexus. Yet, energy and water planners do not treat these important resources as symbiotic “species,” resulting in a lot of waste – something we cannot afford with climate change on the rise.

Floating solar panels atop bodies of water, or the cleverly nicknamed “floatovoltaics,” are a possible solution for both energy and water challenges. The panels help to reduce evaporation of water – critical in hot, dry places like Texas and California – and the water helps to keep the panels cool, increasing their efficiency. Plus, compared to more traditional fuel sources, solar PV requires little to no water to produce electricity. Incorporating more solar energy and relying less on coal or natural gas means greater water savings overall.

Floatovoltaics seem like a win-win solution, but it’s not being deployed on a large scale yet. Some countries and U.S. states have surged ahead in testing this technology. So why isn’t a state like Texas, with big reservoirs, crippling droughts, and lots of solar potential, taking this bull by the horns? Read More »
